Shin's Geass finally breaks him the way the series always threatened it would, and the mecha choreography selling that psychological collapse is better than anything in the original show. The problem is the ending doesn't know what it's trying to say, throwing quantum nonsense at a story that earned its weight through character momentum alone. If you've lived with W-0 this long, you'll watch anyway, knowing you're getting a beautiful funeral for a character arc that deserved a real ending.

With the Ark Fleet destroyed, its crash landing has wiped out a large share of the enemy's troops. The surviving forces of the Knights of St. Michael regroup for one last assault on Castle Weisswolf, and the W-0, joined by their new ally Ashley Ashra, prepare to meet them. Meanwhile Shin, whose Geass has spun out of control, sets out to wipe away his younger brother Akito's existence for good. Akito has promised Leila he will come back alive and will not accept that fate, so the two brothers face each other in a final battle. The film closes the story in a mix of mecha action and science fiction.
